if you can get this done i would consider you my new favorite person in the whole world!
I got the Logitech G15 Keyboard for Christmas and the lcd screen is pretty much useless unless i play the 2 terrable games it automaticaly works with.
there is alot of information at the sight if i remember right they even have tutorials. I also know that there are web sites and forums dedicated to this keyboard and modding the screen.
Good Luck
